Well Enhancer


The Well Enhancer, the world’s first mono-hull vessel capable of coiled-tubing intervention, was built to perform a range of subsea well testing and production flow-back services and is supported by both saturation diving and work class ROV capabilities.

The UK-registered Well Enhancer, a MODU (Mobile Offshore Drilling Unit) class mono-hull vessel, features a 150Tonne Active Heave Compensated multi-purpose tower (MPT) utilized for subsea well operations and a customized coiled-tubing spread within 1,100 m2 of main deck space. She is built to perform a range of subsea well testing and production flow-back services. It features a purpose-built Huisman Tower is over a 7 m x 7 m moonpool and has a traveling block rated to 150Te capacity with active over passive compensation.

The Well Enhancer’s moonpool design, skidding system, and our ability to disconnect and reconnect the control umbilicals subsea enable us to operate safely in harsh North Sea weather conditions that may typically sideline other intervention vessels.

The Well Enhancer operates with our in-house designed Subsea Intervention Lubricator (SIL), a 7-3/8” bore, 10,000 PSI rated, single-trip system. This SIL system converts to 5.5” ID HP riser-to-surface connected to a Coiled Tubing Lift Frame, allowing for a wide variety of Coiled Tubing operations including slickline, eline, Digital Slick Line, braided line /High Definition, coiled hose, and coiled tubing operations in 80-200m water depths.

The Well Enhancer’s 18-man saturation diving spread is rated to 300 meters water depth and, combined with the vessel’s 2 x work class ROVs, provides for full inspection, repair and maintenance (IRM) and light construction services.
